| Abstract/Contents: | "14C-labelled azoxystrobin (Heritage®) was used to investigate uptake and redistribution in creeping bentgrass and tall fescue. Understanding fungicide behaviour after foliar application in turf is vital as turfgrass management requires multiple and frequent cutting and irrigation. Opportunities arise for uptake through the leaf surface, shoot base, roots and via `recycling' if xylem mobile fungicides exude from severed vascular elements after mowing. Azoxystrobin is xylem systemic only and has no vapour activity. Absorbed material moves from the point of uptake, is redistributed evenly throughout the leaf and moves translaminarly into leaves not emerged at the time of application e.g. movement of 14C-azoxystrobin was visualised and quantified throughout new leaves and tillers 46 days after application to the shoot base of only the oldest leaf. Azoxystrobin present in unsprayed foliar tissue is able to diffuse back out on to leaf surfaces. Absorbed azoxystrobin exudes from the cut ends of the leaf blades after mowing and is available for re-absorption." |
